mycobacteriosis

tuberculosis (a mycobacterial infection found in aquarium fish, for example (Mycobacterium marinum and M. fortuitum are known causes). Fish are lethargic, show little interest in food, exhibit wasting, hollow bellies, popeyes, colour loss, deformities, ulcers, frayed fins, yellow or dark nodules on the body and eyes, and secondary infections. Some fish, such as salmonids, may show no external symptoms although the disease is fatal from internal lesions. Mycobacteriosis is a zoonose, a disease capable of infecting humans, entering through skin abrasions and causing skin granulomas. Poor aquarium conditions can allow this infection to take hold. Fish can be treated with proprietary medicines for mild cases, by antibiotics but severe cases may be untreatable. The fish tank needs disinfection. Also called fish TB)
